Description

The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer.

Solution(s)

  • http-openssl-0_9_8-upgrade-0_9_8_s
  • http-openssl-1_0_0-upgrade-1_0_0_f
